LET-OFF MECHANISM FOR LOOMS FOR WEAVING WIIRE.

SPECIFICATION forming part of Letters Patent No. 277,623, dated May 15, 1883. Application filed August 23, 1882. (No model.)

To all whom it may cdnoern:

Be it known that 1, CHARLES SMITH, of Belleville, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Let-ft Mechanism for Looms for Weaving Wire, of which the following is a specification.

My invention relates to wire-weaving looms adapted to be operated by hand, the object being to produce a more uniform tension on the 4 warp-wires while in the process of weaving,

whereby a more perfect cloth is produced.

The invention consists in an improved letoff mechanism for a wire-weaving loom, constructed and arranged substantially as will be hereinafter set forth, and finally embodied in the claim.

The accompanying drawing is a side elevation ofa portion of a wire-weaving loom having my improvements arranged therein.

in carrying out my invention I arrange the parts substantially as shown, A being the frame of the loom; B, the warp-beam secured to the shaft 0; D, a ratchet also secured to said shaft; E, a catch or pawl that engages with said ratchet and is pivoted to the lever F, which latter is fulcrumed upon a section of the frame. A

The lever H-is fulcrumed at K, and carries the adjustable sliding weight L, which is secured to-the said lever by the set-screw M. The levers H and F are connected by a connecting rod or link, G, whereby the two cooperate without any lost motion or power and a positive action is attained.

N is a rope or chain attached to the lever]? and to the catch E, by means of which, when the said lever F is pushed down by the weaver raised by the action of the weighted lever B to engage the catch with the ratchet to keep the warp-beam from unwinding and hold the warp undertension. opened to receive the filling, and when said filling is being driven up by thelay, the lever H vibrates vertically to compensate forthe strain in opening said warp, and allows the filling to be driven up without any extra strain on the cloth, producing a uniform tension on the warp, and thereby makingthe clot-h, when woven, much more uniform and serviceable.

The lever H may be hung below the lever F, and the result he the same.

Having thus described myinvention, what I claim as new, and wish to have secured by Letters Patent, is

An improved let-off mechanism for looms for weaving wire, the same combining therein the warp-beam B, the ratchet D, the lever F, the catch E, the rope N, the weighted lever H, and the rod G, all arranged and operating substantially as set forth.

CHARLES SMITH.
